In this article, we discuss the new constraints that will apply to future, highly dynamic networks and investigate one of the major problems that is likely to affect their deployment: traffic/workload distribution. Starting with a very simple model, we demonstrate that a structure made of undifferentiated subunits will almost inevitably hit a scalability(More)
1.1 The Team Agent Approach This paper describes a novel approach to dynamic distributed parallel processing using a mobile agent-based infrastructure. Our goal is to extend the concept of the Parallel Virtual Machine architecture [8] by using a combination of collaborative and mobile software agents to enable automatic and dynamic configuration of(More)
The future digital battlespace will be a fast-paced and frenetic environment that stresses information communication technology systems to the limit. The challenges are most acute in the tactical and operational domains where bandwidth is severely limited, security of information is paramount, the network is under physical and cyber attack and(More)
The past ten years has seen a urry of research activity into the behavioural control of autonomous mobile robots. Yet despite this effort , many researchers are of the opinion that be-havioural robots are incapable of achieving tasks more complex than simple can collecting, box pushing, herding or moving in formation. If such robots are to gain industrial(More)
Balancing the conflicting demands imposed by a dynamic world on an autonomous robot requires a significant degree of adaptability. This paper describes a multi-layer control system for two cooperating mobile robots, which uses fuzzy logic to adapt the relative importance of a set of reactive behaviours. The fuzzy system therefore acts as an arbiter, which(More)
This paper considers the possible limits of reactive control architectures for autonomous robots, in terms of their non-linear dynamics. This validates work [Gat 94] which has suggested that such systems can manifest chaotic dynamics in their response to unstructured environments. Our work has involved two parallel activities, the first being research and(More)
UK Robotics Ltd. have for some time been working in the area of multiple co-operant autonomous mobile robots. While there are a number of applications in the nuclear, chemical and oo-shore industries that would beneet from such technology, the required science and engineering is only just beginning to be re-alised. The key issues are rstly, how to control(More)
